Fish reef porous concrete prefabricated block

Abstract

The invention discloses a fish reef porous concrete prefabricated block. The prefabricated block consists of an upper part and a lower part, wherein, the contour of the upper part of the prefabricated block is in a cuboid structure, a pair of side faces of the cuboid are respectively equipped with a key and a groove which are nested with another prefabricated block, and the cuboid is longitudinally equipped with a top-down through hole; and four support bodies are arranged at the lower part of the prefabricated block and are respectively positioned at four corners of the lower surface of the cuboid. The fish reef porous concrete prefabricated block has the advantages that by fully applying a spatial geometry principle in design, fish migration channels are naturally generated in the case of block combination, thus being fully applicable to inhabitation and reproduction of various living beings, and realizing perfect integration of ecological restoration and water quality improvement of river channels.

Description

technical field [0001] The invention relates to a concrete prefabricated block, in particular to a fish reef type porous concrete prefabricated block, which is suitable for ecological slope protection of banks of rivers, lakes and reservoirs. Background technique [0002] For a long time, people have only focused on unilateral functional requirements such as flood control, shipping, and bank slope stability for the embankment treatment of rivers and lakes and other surface water bodies. The living space of green plants and aquatic animals cuts off the material exchange between the water area and the land area, which in turn leads to the damage of the aquatic ecosystem of rivers and lakes. Therefore, the ecological construction of hard slopes has attracted the attention of relevant departments. At present, according to the structural and functional characteristics of river and lake bank slopes, new configurations and related engineering technologies suitable for ecological co...

AI Technical Summary

Problems solved by technology

However, for plain water network and other areas, the river channel space is seriously encroached, and most bank slopes are built as vertical mortar block stone bank revetments. Due to the large difference between their mechanical conditions and inclined bank slopes, there is an urgent need for a suitable vertical revetment. New configurations and materials for ecological reconstruction of hardened revetment
